Description

2,5,8,11,14,17,20-Heptaoxadocosan-22-Amine CAS NO 170572-38-0 is a specialized polyether amine, a high-purity chemical building block characterized by its unique oligomeric ethylene oxide chain terminated by a primary amine group. This structure is critical for its role as a versatile linker and modifier, imparting hydrophilicity, flexibility, and reactivity to advanced materials. It is essential for researchers and manufacturers in the pharmaceutical, polymer, and specialty chemical sectors who require precise functionalization and controlled surface properties.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prodrugs, PEGylated therapeutics, and targeted drug delivery systems to enhance solubility and bioavailability.
• Polymer Modification: Acts as a reactive monomer or chain extender in polyurethane, epoxy, and polyamide formulations to improve flexibility, adhesion, and moisture resistance.
• Surface Functionalization Agent: Employed to modify nanoparticles, quantum dots, and diagnostic substrates for improved biocompatibility and stable conjugation with biomolecules.
• Crosslinking Agent: Utilized in the production of hydrogels and smart materials where its hydrophilic polyether backbone and amine functionality enable controlled gelation and swelling behavior.
• Ligand Synthesis: Serves as a precursor for creating chelating agents and ligands used in catalysis and metal ion sequestration processes.
• Cosmetic & Personal Care Ingredients: Incorporated into high-performance formulations as a conditioning agent or emulsifier due to its mild and hydrating properties.

Quality Control

Our 2,5,8,11,14,17,20-Heptaoxadocosan-22-Amine is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and assay, NMR for structural confirmation, and Karl Fischer titration for moisture content, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) documenting full specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (nitrogen or argon) after opening to prevent degradation and maintain product integrity.
